Standard Motor Products Heated Seat Relay
Standard Motor Products Heated Seat Relays: OE-Grade Comfort You Can Count On
When a heated seat stops working, the culprit is often a failed relay — the small but critical electrical switch that controls current flow to the seat's heating element. Standard Motor Products (SMP), one of the automotive aftermarket's most trusted names since 1919, brings that same engineering discipline to every heated seat relay in their lineup. For drivers who rely on seat heat during cold-weather commutes, a direct-fit, OE-quality replacement is not just a comfort upgrade — it's a restoration of a system that was designed into the vehicle from the factory.
The Intermotor Difference
Standard Motor Products offers heated seat relays under their well-regarded Intermotor brand line, which is specifically focused on precision-engineered replacements for both domestic and imported vehicles. Together with the Intermotor brand, Standard provides comprehensive coverage for domestic and imported vehicles. The Intermotor heated seat relay — such as the widely referenced RY-1110 — is built to exacting specifications, rated at 40 amps, featuring 7-blade male terminals, and operating at 12V to match OEM electrical system requirements precisely.
Built for Harsh Conditions
A heated seat relay lives in a demanding environment, subject to temperature swings, vibration, and moisture. Standard Motor Products engineers their relays with this reality in mind. High-quality composite housings protect against harsh temperatures and severe under-hood conditions. High-quality aluminum contacts lead to durability and longevity. And premium epoxy protects against dust, heat, and moisture — all factors that can prematurely degrade an inferior relay.
Where specifications call for it, brass or copper contacts offer extended wear resistance, ensuring reliability even in high-stress applications. This attention to material selection is what separates a relay that lasts from one that fails again within a season.
Certified Quality from a Global Manufacturer
Standard plants are TS16949 and ISO9001 certified, which assures that every part is the right part for the right vehicle. These internationally recognized quality certifications mean that every heated seat relay leaving a Standard Motor Products facility has been manufactured under the same rigorous process controls used by original equipment suppliers. Standard Motor Products relays are designed to exceed OEM specifications for accurate, maintenance-free operation.
With over 10,000 engine, multi-function, and driver-operated switches and relays for import and domestic vehicles, Standard sets the bar for coverage you can count on. Whether you're working on a domestic truck or a European import, there's a strong likelihood that Standard's Intermotor line has the heated seat relay application you need.
